Short answer: the Ascend Acoustics HTM-200SE2 for better sound quality, the Polk T15 for the lower price. The Ascend Acoustics HTM-200SE2 ranks #7 of 87 bookshelf speakers at $368. The Polk T15 ranks #78 at $149, $219 cheaper.
What the Polk T15 offers: Extremely affordable 2-way design that actually measured better at +/-20 degrees vertical off-axis than directly on-axis. In near-field desktop use, the reviewer found the T15 “didn’t sound that horrible,” partly because nearby desk reflections mask the frequency response dip. Watch for: Spinorama analysis reveals what Amir called a “horrific drop in upper mids/lower treble region of 3 to 6 kHz,” likely from tweeter-woofer phase cancellation directly on-axis. Measured impedance ranges from 4-8 ohms, contradicting the specified 6-8 ohm range, and there’s a distortion peak around 400Hz. On- and off-axis response “vary a ton,” making listening position unusually important. The reviewer recommends saving up for the Pioneer SP-BS22-LR instead: “I can’t justify recommending the Polk T15 even though subjective performance was not horrible.”
What the Ascend Acoustics HTM-200SE2 offers: High-quality manufacturer NFS data shows 0.385dB on-axis average absolute deviation, 0.428 listening-window smoothness, and unusually even 80-degree dispersion in both planes. The compact sealed cabinet is easy to place, while the preference score reaches 7.11 with a subwoofer. Watch for: Limited bass is the main tradeoff, measuring 87.9Hz at -3dB, 71.8Hz at -6dB, and 51.3Hz at -12dB; its preference score falls to 4.20 without a subwoofer. The 3.62 sound-power directivity-index standard deviation is respectable rather than exceptional, and the small woofers limit deep-bass output.
Buy the Polk T15 if the price matters more than sound quality. Buy the Ascend Acoustics HTM-200SE2 if sound quality matters more than the price.
